This is Your Brain on a Laser Beam

We are closer to achieving science fiction: your brain--your personality, your mind, your soul, your entire being--may one day be available on a disc. It's mathematically possible for your consciousness to exist without your body. This big idea and the research that supports it is explored in the chapter "Mind Beyond Matter" in Michio Kaku's latest book The Future of the Mind, released Tuesday. Catch him Tuesday night on The Daily Show with Jon Stewart.
